Don’t over-think it so much. You’ll need to be accepting of yourself and live in the moment. Close friendships are a bond to be shared with people who lift each other up and share common interests. If you take less time to focus on the “mechanics” of it and take more time focusing on actually getting to know people, and letting them get to know you… It will be a far easier process. It just takes time, a little trust, and the willingness to open your heart and mind to the right kind of people for you.
